Fart in class

Little Johnny farts in the classroom and his teacher gets really upset and throws him out. He goes and sits outside the class and can’t stop laughing. The principal walks by and sees him sitting outside laughing. He says, “Little Johnny what are you doing sitting here laughing?” Little Johnny says, “I farted in class and the teacher threw me out.” The principal says, “Well then, why are you laughing?” Little Johnny says, “Cause the dumb idiots are sitting in the classroom smelling my fart while they put me outside in this beautiful, clean air.”
